Confused - Creative Elements problem with Category description.

By default the Category description is not shown on the category page?? How can I show the category description ??

Also

But in going into PS/Category each category has the ability to modify/create the Category description. But when you select this button, it displays an error.

Sorry the content area was not found in your page

You must insert the selected module (hook) in the current template, in order for creativeelements to work on this page.

Any ideas how to get over these 2 problems please
